Thisinve'ntion relates to a new and-nui" p'roved stove of that class designed for givingthe draft or products of combustion a eircuitous route in its passagey from the rechamber ofthe stove to the ilue, so as to cause a greater radiation of heat than when there is a direct draft, and which are also designed for heating airfor warming'apartments in` .a building other than that `in which the stove Vis placed. Y l

A represent-s the case of the stove, which case may be of cylindrical4 or other proper form, provided with a base, B, and feet a. C is the iireehamber, placed in the lower part of the ease A, and constructed of tireclay, or fire-brickif desired.

D is a tnbeor pipe, which is fitted4 verti cally and centrally within the case A, andextends down within a short distance of the top of the trechamberor` fire-pot C, and is' closed at its lower end,fbut communicates with the external airby means-of two tubes,

-E E, which extend down at the outer side of,

. the Eire-chamber C, and pass'through the base B, as shown clearly in Fig. 1. l To the inner side of the caseA there are attached anges F, which `preject inward. Two of these iianges are shown in Fig. l, the

Similar letters of referenceindicate likey lower onehavigfa concave under surface and g .the upper one a coxrvex under surface. To the, exterior of the tube or pipe D similar flanges, Y Y, project, both of whichhave concave under 5f surfaces, and thefanges'G Foverlapeachjother+that is to say, vthe outer edges of G ex';

tend beyond vthe outer edges of. F. y f

By this arrangement-'a scrpcntinedirection .3" is givenv the draft of thestove, the products; lof combustion from-the irechamber G,` in

their passage upward, being detlected'iirsttoward the tube or p ipeD, and `then toward 7 lthe case'A, as indicated by thered arrows-in The air passes into the tube or pipe D (see. black arrows)either from thelower par'rof the room in which 'the stove is p1aced, iro1 n, a

cellar or apartment below, or from themouter side of the building, said air heilig heated in its passage upward through D and admitted directly into the room in. which thcstovc is placed, `or carried by suitable pipes into any..

other apartment of thebuilding.`

' Y The serpentine direction given the draft by means of the flanges -FG favors the radiation -of heat directly from the stove while it-,in-

-. sures the heating of the air Ypaslsing upA through D.

The arrangement is` extremely" simple and will effect a great savingin `the consumption"` of fuel'.
